a nurse washing his or her hands

Explanation:

Universal precautions are basically the practices that are considered important to be applied worldwide in medical field. These practices aim to enhance the health of people working in healthcare sector as well as patients. These practices focus on many points that should be followed to avoid the direct contact with the patient's body fluids, by wearing masks, gloves, face shields and goggles.

The system was introduced during 1985–88 but in 1997 it was replaced with a more appropriate system of healthcare safety,called standard precautions.

As per above facts, we can clearly see that usage of gloves, masks and disposing off used needles are clearly among universal precautions. However, a nurse washing his or her hands is not a universal precaution, since it is an example of hand hygiene (although very important in healthcare sector). As per universal precautions, it is more important for a nurse to wear gloves than to was her hands again and again. However, in general body hygiene terms, hand-washing is an excellent health safety measure.

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
